SHE SHEET 2- UNITED STATES FATE T was cor-BE To all whom it may concern:

a citizen of the United States, resident of Minneapolis, county ofHennepin, State of Minnesota, have invented certain new and usefulImprovements in Cot-Beds, of which the following is a specification.

The object .of my invention is to provide a bed designed particularlyfor the use of soldiers at an army post or cantonment and also usefulfor campers generally and for hospital purposes or wherever asubstantial bed of this type can be used.

A further object is to provide a bedwhich will have no loose swingingparts when it is .knocked down or folded which might be broken off andlost in transportation;

A further object is to provide a bed WhlCh can be folded into compactportable form without separation of the parts and when" unfolded orexpanded will be extremely rigid and capable of withstanding the rough,hard usage to which a bed of this type is frequently subjected.

A further object is to provide a bed of strong, durable construction,which will be comparatively light in weight and easily transported fromplace to place.

The invention consists generally in various constructions andcombinations, all as hereinafter described and In the accompanyingdrawings forming part of this specification,

Figure 1 is a side elevation of a bed embodying my invention, V

Fig. 2 is an edge view showing the bed folded,

Fig. 3 is a bottom view of the bed unfolded, ready for use. I

Fig. 4 is a bottom view of the bed folded and strapped together fortransportation,

Fig. 5 is a transverse sectional view showing the position assumed bythe rails and legs when the bed is folded,

Fig. 6 is a detail sectional view, showing the manner of mounting thelegs on the side rail of the bed,

Fig. 7 is a transverse sectional View through one of the rails, showingthe pre ferred manner of securing the flexible bed bottom to the siderails of the bed.

In the drawing, 2 represents a pair of side rails having longitudinalgrooves 3 in their outer faces to receive rods 4 which are inserted intoloops 5 provided in the longituparticularly Specification ofLettersPatent. Patented AiigllQ, 1921. Application filed November 14,1917. Serial No. 201,935. l

dinal edges of the flexible bed bottom 6, composed preferably of canvasor similar material. The upper edges of the rails are preferably curvedto present rounded surfaces 7 on'wliich the bed bottom rests. Forsecuring the rods 5 within the grooves'Tin the rails, I provide a seriesof spring wash ers 8; secured by suitable means,".such as screws 9, tothe rails'and overlapping the grooves 3 and bearing on the loops of thebed bottom, thereby locking the rods in the grooves. WVhen' a load isplaced on the bed bottom, the pull thereon will be imparted to the rodsfor drawing them against'the upper walls of the grooves, the function ofthe spring washers being to hold the rods within the grooves and therebythe strain of the load will be transmitted to .jthe rails. This isavery'simple, economicalmeans for fastening the bedbottom in place, forby loosening the screws the bottom may be easily and or repairs. ,7 1.

I provide the usual number of legs 10 for these rails. These legs haveangleplates 11 mounted on their upper ends andla pping by the outerfacesfof the rails 2 and connected therewith by pivot pins 12. Theseplates allow the legs to be swung inwardly and lie against the underfa'oes of the side rails, as shown in Fig. 2, the angleof'said plates"being such that when the legsare swung to their folded position they willThe parallel and ineontact with the sidera'ils and fit snugly thereon toallo'w the bed to, be folded into compact form. The projecting ends' ofquicklyremoved for substitution 1 the plates have bosses 13 pressedtherein and rivets Hare mounted in the side rails and have heads forentering the recesses formed by said bosses to hold the said legs intheir open or unfolded position, there being siifficient spring to themetal ends of the plates to cause them to bear on the rivet heads withsufiicient pressure to hold them in place. When, however, the leg isgrasped, it may be rocked back and forth on its pivot, the

spring plates sliding over the heads of the rivets to allow the leg tobe moved to its open or closed position.

Each leg is provided with an inwardly projecting lug 15 near its upperend and a similar lug 16 near its lower end. Links 17 are pivotallyconnected at one end with the lower lugs 16 and at their other ends arepivotally connected to bars 18 whichin turnare pivoted to-the lugs andat the point where the and 21 also form a toggle for locking the bars 18in their unfolded position, said links being capable of folding up,jack-knife fashion, as indicated in Fig. 4 for the purpose of allowingthe toggle bars and links to be folded in upon one another and the bedcontracted to a compact or folded position. There are, of course, a pairof toggle links and bars. at each end of the bed between the oppositelegs at their front andrear ends and in setting up the bed, it is onlynecessary to draw the rails apart, straighten the toggle links 17 and 18and lock them in their expanded position by straightening the links 20and 21.

I prefer to provide straps 23 mounted on the legs by means of loops 24by means of which the legs and rails may be bound securely together fortransportation of the bed. *When the legs are unfolded, the ends thereofwill bear squarely on the under faces of the rails, as indicated in Fig.6, and form a substantial support therefor, the legs being swung out toa point where they will be slightly out of the perpendicular to preventaccidental collapse and spreading of the opposite legs will bepositively prevented by the arrangement of the toggle bars and linksbetween them.

In various ways the details of construction herein shown and describedmay be modified and still be within thescope of my invention.

A bed of this type is particularly valuable for army or camp use fromthe fact that there are no loose swinging parts, such as hooks orbraces, when the bed is folded to be broken or torn off intransportation. Every member folds into compact form, the legs beingheld at both ends and prevented thereby from swinging or swaying andbecoming damaged whenthe bed is folded for transportation.

I claim as my invention:

1. A folding bed comprising side rails, a flexible bottom securedthereto, legs for said side rails, flange plates secured to the upperends of said legs and embracing the corners thereof and projectingupwardly on each side of said rails and having a pivotal connectiontherewith at one side of the longitudinal axis of said legs, said plateshaving bosses formed therein, said rails having heads for entering saidbosses for temporarily holding said legs in place and the upper ends ofsaid legs be ing seated against the underside of said rails when saidlegs are unfolded.

2. A folding bed comprising side rails and a flexible bottom securedthereto, legs pivoted on said rails, bars pivoted one upon the other andhaving a pivotal connection at one end to one end of said legs and apivoted link connection at their other ends with the other ends of saidlegs, and toggle links having their inner ends pivoted together andtheir outer ends pivoted on said bars, said links, when in alinement,locking said bars intheir expanded position. r

8. A folding bed comprising side rails and a flexible bottom securedthereto, legs for said side rails, said legs being mounted in the planeof said side rails to swing up against the under surface thereof whennot in use and having theirupper ends bearing on the under surfaces of.said rails when turned down to a supporting position, bars pivotallyconnected with the upper portions of the op posite legs and projectinginwardly and hav-= ing their inner portions pivoted together, and linkspivotally connecting the inner ends of said bars with the lower portionsof the opposite legs for bracing and supporting the upper and lower endsof said legs when they are swung down to a working position, and togglelinks connecting the upper portions of said bars and adapted, whenunfolded, to lock said bars in their open, position.

In witness whereof, I have hereunto set my hand this 2d day of November1917.
